HRHEAT REFLECTIVE

Chemcast HR is the acrylic sheet that reflects up to 50% of the infrared radiation from the sun and at the same time it blocks up to 99% of UV radiation.

Chemcast HR allows you to save up to 25% of energy (BTU's) in air conditioning in boats, yachtsor catamarans (40% of glazing).

Feel more comfortable under Chemcast HR protection even in domes and acrylic roofs.

Advantages and Benefits

Lighter weight than glass.

Easy to fabricate.

Full protection against UV solar radiation.

High infrared radiation reflectivity.

High clarity in a wide range of colors.

Available in a wide range of sizes.
